A new method based on photographic sampling coupled with in situ observations was applied to 53 stations along the French Mediterranean coast, to assess the integrity of coralligenous reefs affected by different levels of anthropogenic pressure. The conservation state of the assemblages characterizing these habitats was then assessed by an index - the INDEX-COR - that integrates three metrics: (i) the sensitivity of the taxa to organic matter and sediment deposition, (ii) the observable taxonomic richness, and (iii) the structural complexity of the assemblages. The sensitivity of INDEX-COR was tested and showed good correlation with the Level of Pressure calculated for each station according to expert judgment and field observations.
一种基于摄影采样并结合现场观测的新方法应用于法国地中海沿岸的53个站点，以评估受不同程度人为压力影响的珊瑚礁的完整性。然后通过一个指数——INDEX-COR来评估表征这些栖息地的群落的保护状态，该指数整合了三个指标：(i) 分类群对有机物质和沉积物沉积的敏感性，(ii) 可观察到的分类丰富度，以及(iii) 群落的结构复杂性。对INDEX-COR的敏感性进行了测试，结果表明它与根据专家判断和实地观测为每个站点计算的压力水平具有良好的相关性。
